Hello everyone,
I have a board (820-4924-A) without any signs of corrosion and no liquid spilled on it. From one day to another it didn't turn on.
The light of the Magsafe connector turns green and then orange. The board draws 350mA with a disconnected battery.
I have measured the following signals so far:
What should I test next?
